Schist vs Coal

Schist vs Coal Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Schist and Coal Reserves. Schist is a medium grade metamorphic rock with medium to large, flat, sheet like grains in a preferred orientation. Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Schist vs Coal information and Schist vs Coal characteristics in the upcoming sections.

Schist vs Coal Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Schist vs Coal characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Schist and Properties of Coal. Learn more about Schist vs Coal in the next section. The interior uses of Schist include Decorative aggregates, Floor tiles and Interior decoration whereas the interior uses of Coal include Not yet used. Due to some exceptional properties of Schist and Coal, they have various applications in construction industry. The uses of Schist in construction industry include As dimension stone, Building houses or walls, Cement manufacture, For road aggregate, Roadstone and that of Coal include Cement manufacture, For road aggregate, Making natural cement, Steel production.

Schist is available in black, blue, brown, dark brown, green, grey, silver colors whereas, Coal is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Schist is Layered and Shiny and that of Coal is Veined or Pebbled. Properties of rock is another aspect for Schist vs Coal. The hardness of Schist is 3.5-4 and that of Coal is 1-1.5. The types of Schist are Mica Schists, Calc-Silicate Schists, Graphite Schists, Blueschists, Whiteschists, Greenschists, Hornblende Schist, Talc Schist, Chlorite Schist, Garnet Schist, Glaucophane schist. whereas types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Schist is white while that of Coal is black. The specific heat capacity of Schist is Not Available and that of Coal is 1.32 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Schist is impact resistant, pressure resistant, water resistant whereas Coal is heat resistant.
